Nitheesh George is conducting DNS (Direct Numerical Simulation) studies to predict the thermal plume behaviours and smoke movements in a confined space, which can be like a sub-canopy region. The plume originates from a line heat source of length, located at the centre of the bottom surface and rises until it impinges on the top surface and spreads laterally to produce a buoyant fluid layer beneath the top surface. Since the region is confined, the continuous supply of buoyant fluid forces the layer downwards, until it reaches the bottom surface, where the flow is said to be at the asymptotic state.
